Effects of RIPC-plasma on hypoxia–induced damage of HUVEC cells. a Quantification of LDH-activities as a marker for cell damage in HUVEC cell culture media. Culture media were supplemented with 5 % plasma (T0, T1 and T2) from the various volunteers (#1–#10) and LDH-activities were measured after 24 h of hypoxia. b Relative LDH-activities in culture media of HUVEC cells after 24 h of hypoxia. Cell culture media were supplemented with plasma T0, T1 or T2. Hypoxia–induced cell damage is significantly reduced by the addition of plasma T1. Numbers in the columns show the numbers of different plasma samples used. Columns display the mean ± SEM
